RF circuit switch chip, RF circuit, antenna device and electronic equipment

Abstract

Embodiments of the present invention provide a radio frequency circuit switch chip, a radio frequency circuit, an antenna device and electronic equipment. The radio frequency circuit switch chip includes: a first switch, a second switch, a third switch, a first combiner and a second combiner, the first switch is used for transmitting intermediate frequency signals and high frequency signals, and the second switch is used for Transmission of low-frequency signals; when the first switch outputs high-frequency signals and low-frequency signals to the first combiner, the third switch connects the first combiner to the second combiner; the first combiner Carrier aggregation is performed on the high frequency signal and the intermediate frequency signal to generate a first aggregated signal, and the second combiner performs carrier aggregation on the first aggregated signal and the low frequency signal; when the first switch transmits the high frequency signal or the intermediate frequency signal to the When the third switch is used, the third switch connects the first switch and the second combiner, and the second combiner performs carrier aggregation on the high-frequency signal or the intermediate-frequency signal and the low-frequency signal.

Description

technical field [0001] The invention relates to the communication field, in particular to a radio frequency circuit switch chip, a radio frequency circuit, an antenna device and electronic equipment. Background technique [0002] With the development of communication technologies, mobile terminals can support more and more communication frequency bands. For example, an LTE (Long Term Evolution, long term evolution) communication signal may include a signal with a frequency between 700 MHz and 2700 MHz. [0003] The radio frequency signals that the mobile terminal can support can be classified into low frequency signals, intermediate frequency signals and high frequency signals. Wherein, each of the low-frequency signal, the intermediate-frequency signal and the high-frequency signal includes a plurality of sub-frequency band signals. Each sub-band signal needs to be transmitted to the outside world through an antenna. [0004] Thus, a carrier aggregation (Carrier Aggregat...
